SPECIFICATION forming part of Letters Patent No. 551 ,330, datedDecember 10, 1895.

Application filed May 9, 1895. Serial No. 548,794. (No modeld To allwhom, it may concern:

Be it known that we, JOSEPH A. Coca-IRAN and JAMES BRANT, of FountainBluff, in the county of Jackson and State of Illinois, have inventedcertain new and useful Improvements in Fans; and we do hereby declarethe following to he a full, clear, and exact descrip' lion of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

Our invention relates to an improved fan; and the object of the same isto provide'an improved driving mechanism therefor which will actuate thefan as well in an upwardlyextending position as in a depending or hanging position.

A further object is to provide an improved regulating mechanism as wellas an improved mechanism for starting and stopping the mofor.

Our invent-ion consists of the novel features of constructionhereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a perspective view of thefan. Fig. 2 is a plan view with the lid of the mo tor-box thrown open.Fig. 3 is a sectional plan view showing the mechanism for regulating andstopping and starting the motor. Fig. ii: is an elevation of the fan ina depend ing position. Fig. 5 is a vertical'crosssectional view showingthe adjustment of the brake-governing mechanism. Fig- 6 is a verticallongitudinal sectional view on line 6 O of Fig. Fig. 7 is across-sectional View on line 7 7 of Fig. 3, looking in oppositedirection from that indicated in Fig. 5.

A indicates the motor'casing and B the lid therefor. The train of gearextending from the main spring G leads up to and terminates in gear 1),which actuates pinion E upon the lower end of the spindle F, whichlatter at its upper end projects through opening F formed in the lid ofthe casing and is constructed with a socket to accommodate the shaft ofthe fan presently to be described. The socket is provided upon its outerside with the projection II, which is adapted to be engaged by theturned end I of controlling-lever J fulcrumed to the frame of the motorand projected at the free end out of the casing and confined by notchesK so as to hold the same in either a starting or stopping position. henholding the motor still the said turned end I engages the projection llof the spindle and prevents the latter from rotating, while whendisengaged the same is free to rotate as will be readily understood.

For controlling the speed of the motor we provide the swinging arm L,pivotally supported at its outer end and at its inner end adapted tobear upon the spindle of the fanshaft, the same being normally heldthereagainstby the coiled spring M. This spring is connected at itsinner end by cord M to shaft in, which is driven by gear 21, the latterreceiving its impetus from the pinion 0 on the initial shaft. Thus whenthe spring C is wound up the gear a and shaft on are rotated, therebywinding thecord M on the latter and expanding spring ilLso to causebrake-arm L to bear strongly against the fan-rotating shaft, and preventthe rapid rotation thereof when the spring is exerting its full strengthon the retating mechanism, while as the strength of said springdecreases by the nncoiling the said cord M" slowly unwinds, therebyproviding a differential governor or brake for the motor.

As an additional regulating device for controlling the fan-shaft andcausing the same to move either fast or slow irrespective of how fastthe initial spring may go we provide the turning-shaft )7, having aprojected arm connected by coiled spring 0 to arm L, and theturning-shaft N is controlled by the angular handle P extending outwardthrough the slot in the casing top and held by the notched bar Q in thedesired position. Thus it will be seen that by drawing the said handleto one side the shaft carrying the arm will be turned backward, thuscausing the spring 0 to exert a pull upon arm L, thus reducing thepressure of the latter upon the shaft-spindle.

The shaft R of the fan is provided at its outer end with the T-head R,and the fanblades S are held thereto by a socket S fitting over the armsof the T-head. Pins T serve to hold the fans in the desired positionupon the head so that the blades may be disposed at an angle to theshaft or parallel therewith, and we prefer when the fan is arrangedabove its casing and motor to have the blades arranged parallel, whileif the fan is arranged as a hanging fan then we desire to arrange theblades at an angle as indicated in Fig. 4:.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. The combination of a motor, a fan operating shaft actuated by themotor, and a brake connected with and operated by the winding mechanismof the motor, substantially as shown and described.

2. The combination of the spring motor mechanism, the fan operatingshaft actuated thereby,a brake,the spring connected thereto, the cordleading from said spring, the shaft to which the cord is connected, andthe gear for rotating the shaft extended to the motor, whereby when themotor is wound up the cord will be wound upon the shaft, thus increasingthe pull of the spring upon the brake, and as the motor unwinds, thecord will also unwind and thus decrease the tension of the spring on thebrake, thereby securing uniformity of speed of the fan, substantially asdescribed.

3. The combination of a motor mechanism, a spindle carried thereby, anarm pivotally supported at one end and at its free end adapted to bearagainst the spindle so as to govern its movement, a spring arranged tocause the arm to bear on the spindle, a second spring connected with thearm, and a mechanism for controlling said second spring so as tocounteract the effect of the first named spring, substantially as shownand described.

4. The combination of a motor mechanism, a spindle actuated thereby, abrake arm pivotally supported at one end and at its free end adapted tobear against the spindle, the spring for pulling the arm against thespindle, the shaft carrying an arm, a spring connecting the arm with thesaid brake arm for counteracting the effect of the first named spring,the handle extending from the shaft for turning it, and the holder forconfining the handle at the desired adjustment.

In testimony whereof we affix our signa tures in presence of twowitnesses.
